Questions about this item

Does the GreenTech B31N1912 C31N1912 42WHR battery come with installation tools or must they be bought separately?

Only the battery itself is supplied; screwdrivers or pry tools for opening the VivoBook chassis are not included and must be sourced separately.

How do I choose between the listed part numbers B31N1912, C31N1912, 0B200-03680200 and 0B200-03680000 for my ASUS VivoBook?

All four numbers refer to the same 11.55 V, 3640 mAh, 3-cell pack; match any one of them to the label on your original battery to confirm fit.

What does the 42 Wh rating mean for real-world runtime in a VivoBook 14 E410MA?

The 42 Wh capacity restores the original factory runtime, delivering roughly the same hours of mixed use as the OEM battery when new.
